I have finally reached 25 million credits for Seti so I am now scaling back and will concentrate on some of the other projects. Both Asteroids and ClimatePrediction need to catch up. In the case of ClimatePrediction they tend to go from feast to famine (ie lots of work to none) quite regularly. Asteroids have a CUDA app but because it does floating point maths it runs rather slowly. Both AMD and Nvidia limit the floating point capability of their consumer grade cards.
The farm is running during the day but the main GPU crunchers are usually off. Now that the dual Nvidia-GPU machine has been updated to GTX750Ti cards it may get to run during the day. I have already listed the two GTX660's on eBay.
Depending on how the 750Ti cards work out I may replace the remaining GTX660 cards. I have one GTX660 in each of the 6 core/12 thread crunchers.
Also on the shopping list are GTX970's to replace the GTX670's that are in the GPUgrid crunchers. I looked at them last week but decided they were a bit too expensive at the moment.
Project news - GPUgrid
They've decided to move to a CUDA 6.5 app and are dropping their 4.2 app. This fits with Nvidia ceasing support in their drivers for pre-Fermi cards. Given they are up to Maxwell architecture I expect Nvidia will drop support for the Fermi-based cards fairly soon.
